Hello,

I have been trying to build my Elixir / Phoenix app but can seam to find a why to specify a newer version of the OTP release.

Could someone please indicate me what what options do I need to configure to fix this build issue?

This is app requires the following dependencies

{:broadway_kafka, "~> 0.4"},

{:snappyer, "~> 1.2"},

# nixpacks.toml
[variables]
MIX_ENV = 'prod'
PHX_SERVER = 'true'
ELIXIR_ERL_OPTIONS = '+fnu'
RAILPACK_ELIXIR_VERSION = '1.18'
RAILPACK_ERLANG_VERSION = '27.3'

[phases.setup]
nixPkgs = ['...', 'erlang', 'cmake', 'gcc', 'libtool', 'patch']

[phases.install]
cmds = [
  'mix local.hex --force',
  'mix local.rebar --force',
  'mix deps.get --only prod',
]

[phases.build]
cmds = ['mix compile', 'mix assets.deploy', 'mix release']

[start]
cmd = "mix ecto.setup && mix phx.server"
